Innova Champion Discs is offering this mini Swoosh stamped glow in the dark Champion material Cobra as a tournament fund raising disc. I am offering these to help support several events: the Ft. Steilacoom Open, the Duos Duel in the Desert, the US Masters and the European Open. These discs are not event stamped because they all have issues with the centers of the flight plates. Some are better than others but they are all great throwers.
